Same thing here. The machine crashes on weekends shortly after 01:00 after I had upgraded to 2.4.25 and 2.4.26. I disabled smart as you suggested, but too recently to be sure that it was the cause. It could just be related to additional load caused by cron jobs? Any confirmed solutions yet? Sebastian
